People here still can't figure out roundabouts.

We just got one in rural MN and no one can figure it out. It's terrible. I was in it yesterday and a car literally stopped, in the circle, to let other cars in. WTF Alexandria!

Ha! Just the other day I saw a dude change lanes twice in the course of 10 feet, and I thought "hey they're improving!"

We have a tiny little traffic circle in my neighborhood, about a block from my house. People don't seem to comprehend that when making left turns, YOU HAVE TO GO ALL THE WAY AROUND. You can't cut left before the circle, like you think you're sneaky. I have almost hit so many people because the overgrown bushes on the corner make it a blind turn. Maybe the people in my neighborhood are extra stupid.

OMG! This!

They're EVERYFUCKINGWHERE in my neighborhood, and a good 20% off the population has no fucking clue... If we all go in to the RIGHT it works for everybody.

Of course it would help if DOT didn't do Boneheaded moves like putting stop signs at 2/4 of the entries. Cuz then people are like, who has the right of way now???

I'm more in roadway and dabble in traffic occasionally.

Full disclosure, not a professional engineer. Only a lowly designer

Oh well then I won't talk to you aNY more! I love our roadway people. My husband is in site civil, and the more other people design things, the less I have to. I hate design. I'm a pe, ptoe but functionally I'm more of a planner. Lots of studies and modeling.

I'll jump into this part of the convo. :-)
I'm a trained/licensed LA with more experience in land planning, working in an office now that includes PEs. I 'lol have to check this out and see if I'm a fan or not.

I noticed this in a few residential areas of Ballard and it completely baffled me. The point of the circle is to get everyone to slow down! The stop signs make it extra confusing! GET OFF MY LAWN!!

Why is that better than just having four entrances so everyone is entering from the right lane? For example if you're headed east and want to get on the highway going south you get on before the highway and if you're going north you pass over the highway and still enter from the right lane and the entrance ramps curves. Then no lights are needed! (Hope I explained that well).

You're talking about a cloverleaf? The main thing is usually that they take up a shitton of space. And they create a weave on the highway which can be bad depending on the volumes. And if the local street has bikes or peds all those merges and diverges suck. (Not that a ddi is perfect)

cloverleafs are the SHIT! I LOVE cloverleafs!

We just got a divergent diamond intersection on the exit by our house and it is sooooo cool! I was super skeptical but now everytime I drive it I'm like "this is awesome".
